Eh, what about the SuperPET? Schematics available AFAIK. Good start IMHO. One remark: as engineer I never liked the solution of powering the 6502 off for shutting it down. 

That card is indeed the Liber809 as noticed by others. I asked the designer for info but no schematics or what ever and he charged $70 for the whole for the card.

The 6502 of Atari is different, one thing I am quite sure of: it could be tri-stated.
